Air capture hood manual

grilles. Capture hoods are available in a kit with one 2 ft. 2 ft. ( mm mm) fabric hood, frame, and base assembly. Alternate hood sizes are available. Descriptions and part numbers can be found in Table 2 of Chapter 2 of this manual. Velocity Matrix The velocity matrix is used to obtain area-averaged multi-point air velocity measurements. for air conditioning and ventilation systems. Thanks to its interchangeable flow hoods, the testo can be used for air inlets and outlets of various sizes. With the additional App (Android/iOS), the readings can be conveniently displayed on a tablet or smartphone, and in addition a measurement can be started, stopped and saved via the App. A one- or two-sided overhead hood that receives rising hot air or gas. Capture Velocity The velocity of air induced by a hood to capture emitted contaminants external to the hood. Coefficient of Entry (C e) A measure of the efficiency of a hood's ability to convert static pressure to velocity pressure; the ratio of actual flow to ideal flow.

When using a capture or receiving hood, the hood should be located as close to the contaminant source as possible. Reducing the amount of contaminants generated or released from the process reduces ventilation requirements.
